IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 184,441, dated November14, 18x76; application led I August 2l., 1876.

To all Iwhom it may concern:

Be it known that l, WILLIAM B. SIURGIs, of Shelbyville, in the county ofShelby and tate of Illinois, have invented a new and useful Improvementin Cultivators, of vwhich the following is a specification Figure l is avertical longitudinal section of my improved cultivator, taken throughthe line w x, Fig. 2. Y Fig. 2 is a top view of the same. Fig. 3 is adetail section taken through taken through the line z z, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an construction and effectivein operation, being easily adjusted, guided, and controlled.

The invention relates to the construction and arrangement ofparts-namely, the short axles, socket and set screws, front and rearbraces, the curved bar, to which the frame of ling of thecultivator-beams, all as hereinafter described and claimed.

A are the Wheels, which revolve upon the outer arms of the crank-axlesB. The inner arms of the crank-axles B pass through holes in the ends ofthe bar C, where they are secured in place adjustably by set-screws D.rlhe bar C is arched or bent at an angle to raise its middle part, sothat the machine may be drawn over tall plants Without injuring them. Tothe center of the bar C is secured the tongue E, the rear end of whichprojects in the rear of the said bar. To the bar C, upon the oppositesides of and equally distant from the tongue E, are secured the two barsF by clips G. The forward and rear ends of the bars F are connected witheach other and with the tongue E by rods or long bolts H. l'lo each endof the forward rod or bolt H are secured the upper ends of two braces, IJ. The lower end of the brace l is placed upon the outer part of theinner arm of the crank-axles B, close to the inner sides of the vends ofthe bar C. The lower ends of the braces J and of other braces, K, areplaced upon the end of the said inner arms of the said axles, restagainst shoulders formed upon said axles, and

are secured in place bynuts L, screwed upon the ends of the axles, asshown in Figs. l and 3. The upper ends of the braces K are secured tothe ends of the rear rod or bolt H. Upon the innerarms of thecrank-axles B, between the ends of the braces J K and the ends of thebrace I and bar C, are placed blocks M, the upper and lower sides ofwhich are grooved, as shown in Fig. vi, and through its forward part areformed three (more or less) holes'to receive the bolts N, which also.passthrough the ends of the straps O, placed above and .below saidblocks. The rear ends of the lstraps O are secured to the upper andlower sides of the forward ends of the plow-beams P, so that the rearends of said plow-beams may have a free lateral and vertical movement,to enable the plows to be readily guided.

'To the opposite sides of the rear parts of the plow-beams P areattached the upper ends of -the standards Q, the draft strain upon whichis sustained by the braces R, the upper ends of which are bolted to thebeams P, sev- 'eral holes being formed in the said ends to receive thesaid bolts, to enable the pitch of the plows to be adjusted as required.The rear ends of the braces R pass through holes in the standards Q, andhave holes formed in them to receive wooden pins, which are made of sucha size as to sustain the draft-strain, but which, should the plowsstrike an obstruction, will break, and allow thev standard to swing backwithout being broken. S are the plow-plates, to the rear sides of whichare bolted or riveted blocks T, the rea` sides of which are grooved orconcaved longitudinally, to fit upon the forward sides of the lower endsof the standards Q. The blocks T have holes formed through them toreceive the bolts by which they are secured to the standards Q, and havenotches formed in their forward sides to receive the heads of saidbolts.v The holes through the standards Q are made larger than the boltsthat pass through them, so-

that the plows may be adjusted to throw the soil toward or from theplants, as may be desired. To the plow-beainslD are attachedupwardly-projecting hooks U, to hookupon the braces K, to support theplows away from the ground when turning around and passing from j placeto place.

To an eye formed upon the lower end ofthe y' brace KV or bar C, orconnected with the arm of the axle B, is pivoted a bar, hook, or link,V, to the other end of which is pivoted the lower end of the bar W. Theupper end of the bar Wis pivoted to the end of thedoubletree X, which ispivoted atts center to the tongue E by a bolt, Y. The bolt Y isstrengthened against thedraft-strain bya strap, Z, secured to its end,and the rear end of which is secured by the bolt that secures the tongueE to the bar C. Several holes are formed in the bars W to receive theWhiftletree-clevis, so that the point of draft attachment may beadjusted higher or lower, as may be desired.
